Final answer:
The restore period of an Azure AD user is 30 days, during which the user's account can be restored if deleted.
Step-by-step explanation:
The restore period of an Azure AD user is 30 days. During this time, if a user is deleted, their account can be restored within this period. After the restore period, the user's account cannot be restored.
For example, if a user is accidentally deleted from Azure AD, the administrator has 30 days to restore the user's account and associated data before it is permanently deleted.
